IMPROVEMENT IN THREAD-CUTTERS AND THIMBLES COMBINED.

Specification forming part of Letters Patent No. 128,195, dated June 18,1872; antedated June 12, 1872.

To all whom it may concern:

Beit known that I, BASIL M. WILKERSON, of Tuscaloosa, in the county ofTuscaloosa v and State of Alabama, have invented a new and ImprovedThread-Gutter and Thimble thimbles, for cutting off, and by the act ofcutting, at the same time pointing or sharpening the end of the threadfor inserting in the eye of the needle.

My invention consists in a peculiar threadcutting plate applied to athimble, the plate having all its exposed edges blunt, and itscutting-edges formed by cutting or filing trans versely to one edge andat an angle to the face of the plate, a nick or notch, the length anddepth of which are greater upon the side at which the thread enters thanupon the opposite side, the nick on one side of the plate being in theform of a gradually-taperin g angular groove, terminating at the edge ofthe plate in two minute sharp cutting-edges which meet at an angle, suchedges and angle being at that part where the groove is cut entirelythrough the plate.

The drawing is a perspective view of my improved thimble. A is anordinary thimble.

.B is my improved steel-plate let into a notch in the side flush withthe inner surface and secured by a screw, or in any other way. Saidplate has a notch and groove, constructed as above stated, and havingthe walls beveled, so that the cutting-edge is flush with the innersurface, or thereabout. The plate is not so thick or the notch so deepbut that the thread can be pressed on the cutting-edges by the thumbpressing against the surface of plate B. The thimble is worn with thenotch frontin g the thumb the thread is laid in the groove and pressedinward against the edges of the cutter by the thumb of the hand on whichthe thimble is, and pulled by the other hand against the cutter, in suchmanner as to be cut off and trimmed obliquely onthe two opposite sidesof p the thread, forming a tapered point, which will enter the eye ofthe needle readily. These cutters may be attached to sewin gmachines,spools, 850.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The thread cutting plate B, having its exposed edgesblunt and its cuttingedges formed by cutting or filing transversely to ablunt edge, and at an angle to the face of the plate a nick or notch,the length and depth of which are greater at the side at which thethread enters than at the opposite side, and operating to taper orsharpen the thread in the act of cutting it, substantially as described.
